Resumen
CPS (Cyber Physical Systems) is an approach often adopted for improving real-world activities by utilizing data. It also can be used to improve customer experiences in service applications by analyzing customer behavior, captured by sensing devices and by supporting utilization of that data by the service providers, to improve the system. In developing such systems, no method has been established to systematically evaluate the impact of individual component design on the user experience. Knowledge Experience Design is a method for distilling and validating information that affects the quality of the user experience by focusing on user activities and underlying knowledge. This methodology has been applied to a system for a museum, in which visitor activities are observed by sensing devices, to aid the Curator?s awareness for improving museum services. As a result, a cooperative process for designing devices and user experience as a service was derived, in which competing interests of lower power consumption and user experience improvement have been attained. The proposed design method can be used for the co-design of systems that are built on the close coordination of hardware devices and software applications, for providing value-oriented services to users, which aids realization of CPS oriented to evaluating and improving such environments.
